Abstract

A method of treating an aqueous system is disclosed which comprises adding thereto a phosphonium compound of the formula: <CHEM> wherein each R, which may be the same or different, is a C1-C6 alkyl group which is optionally substituted by, say, a hydroxy, ethyl, aryl or cyano group, or a phenyl group which is optionally substituted by one or more C1-C4 alkyl groups, R1 is a C8-C18 alkyl group and X is chlorine or bromine and a straight chain aliphatic aldehyde.
